[FEATURE] Optimize nginx config files for vhost

[Chris-West-2]

What's needed and why?

We have a quite large nginx setup and tried to convert it over to bunkerweb for the additional WAF protection.
We saw that the system itself creates a multitude of configuration files per vhost.
This leads to an increased processing time of nginx -t command.
At a certain point (round about 130 vhosts) nginx -t doesn't finish testing within 3 minutes and breaks down.
Because of this bunkerweb falls to fall back and bunkerweb is no longer functional.
Someone might ask why so many hosts.
We have a software solution that works with white label solutions to provide services for our customers.
